Cálculo de logaritmo em qualquer base. Algoritmo lento, possivelmente pela quantidade exorbitante de divisões e utilizações de Math.sqrt (que não chegam a ser tão frequentes como o número de divisões, mas ainda é alto: por volta de 50 a cada cálculo de logaritmo)

def log(n, m)
# Verifica valores de entrada
if m == 0 # Não existe logaritmo de 0, logo, adequa valor
# ao retornado pelo Math.log: -Infinity
return -1.0/0.0
